説明
Mercury(I) bromide or mercurous bromide, Hg2Br2, is a compound that changes color from white to yellow when
heated and fluoresces a salmon color under UV light. It is used in acousto-optical devices. A very rare mineral is kuzminite, Hg2(Br,Cl)2. Mercury(I) bromide is formed through the oxidation of elemental mercury with elemental bromine or
via the addition of sodium bromide to a solution of mercury(I) nitrate.
化学的特性
white, odorless, tasteless powder(s); tetr; sensitive to light (darkens); decomposed by hot HCl or alkali bromides; becomes yellow when heated, returns to white color when cooled; prepared by oxidation of Hg with Br2 or as a precipitate by addition of NaBr to HgNO3 solution [KIR81] [HAW93] [MER06]
一般的な説明
White, odorless powder. Darkens on exposure to light. Sublimes at high temperatures.
空気と水の反応
Insoluble in water.
反応プロフィール
MERCUROUS BROMIDE is incompatible with the following: Acetylene, ammonia, chlorine dioxide, azides, calcium (amalgam formation), sodium carbide, lithium, rubidium, copper .
健康ハザード
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
火災危険
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
